Unicode support in cStringIO would require a new implementation since the machinery uses raw byte buffers.
Not necessarily. You could add a flag saying that whether those bytes represent Unicode strings or not. If they do, you pick an encoding of your choice (perhaps unicode-internal), and convert the existing bytes to that encoding on first sighting of a Unicode string (assuming that everything so far is in the system encoding). When returning the bytes to the user, you build a Unicode object if the flag is set. Of course, you'd still have to touch every method, to analyse the flag... Regards, Martin
